对比中美钢闸门规范，发现两国规范在计算面板兼作主（次）梁有效宽度时建立的力学模型存在差异：中国规范考虑了应力分布不均匀性，而美国规范没有考虑；根据薄板稳定理论确定面板有效宽度时，两国规范所采用的四边约束，以及考虑的塑性程度、残余应力和材料缺陷的影响也不相同。针对两国规范的差异，建议按美国规范设计时应根据构件的截面形状（工字形、 T形等）、截面类型（紧凑型或非紧凑型），以及受力状态（受压或是受弯）来选取宽厚比限值计算面板兼作主（次）梁翼缘的有效宽度。

By analyzing the steel gate codes of China and America, the differences are found in building the mechanical model of gate to calculate the effective width of skin plate. The non-uniformity of the stress distribution is considered in Chinese codes, but the others not. Even the stability theory of plates is both used to determine the effective width of skin plate in two countries' codes, they are also differences in considering the edge conditions and the compact of plasticity, residual stresses and material defects. It is recommended that the appropriate width-to-thickness ratio shall be selected to calculate the effective width of skin plate in gate design according to cross-sectional shape (I-shaped, T-shaped or others), section type (compact or non-compact) and stress state (compression or bending) when designing according to American codes.
